Bahāʾ al-Dīn, in full Abū al-Maḥāsin Yūsuf ibn Rāfiʿ ibn Shaddād Bahāʾ al-Dīn (born 1145, Mosul, Iraq—died 1235, Aleppo, Syria), Arab writer and statesman, author of the Sirat Salāḥ ad-Dīn (“Life of Saladin”). He was first a teacher at Baghdad and then professor at Mosul.

In July 1188, after making the pilgrimage to Mecca, Bahāʾ al-Dīn entered the service of Saladin, who was waging war against the Christians in Palestine. Bahāʾ al-Dīn sought Saladin’s favour by urging him to the vigorous prosecution of this war and presented him with his treatise on the laws and discipline of holy war (jihad). He remained constantly devoted to Saladin and was employed on various embassies and in departments of the civil government, being appointed judge of the army and judge of Jerusalem. After Saladin’s death Bahāʾ al-Dīn remained the friend of his son Malik aẓ-Ẓāhir, who appointed him judge of Aleppo. There he employed some of his wealth in the foundation of colleges. When Malik aẓ-Ẓāhir died, his son Malik al-ʿAzīz was a minor, and Bahāʾ al-Dīn had the chief power in the regency, using it for the patronage of learning. He lived in retirement after the abdication of Malik al-ʿAzīz. Bahāʾ al-Dīn’s most important work is his biography of Saladin, the best account of the sultan’s life.
